'1 Claim.

The present invention relates to new and useful improvements in torch heads particularly ,for acetylene torches and has for its primary object to provide, in a manner as hereinafter set forth,

a device of this character embodying a novel construction, combination and arrangement of parts through the medium of which circular, straight and rivet cutting may be accomplished with a single torch.

Another important object of the invention is to provide a torch head of the character described including a swingable nozzle, together with novel means for mounting said nozzle.

Still another important object of the invention is to provide a torch head of the character set forth which is adapted for bevel cutting and which may be used in what have heretofore been considered substantially inaccessible places` Other objects of the invention are to provide a torch head of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specication, taken in connection with the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:-

Figure 1 is a view in side elevation of a torch head constructed in accordance with the present invention. y

Figure 2 is a view in top plan thereof.

Figure 3 is a. detail view in side elevation of the swingable nozzle.

Figure 4 is a horizontal sectional view, taken substantially on the line 4 4 of Figure 1.'

Figure 5 is a detail view in vertical section through the swingable nozzle.

Figure 6 is a detail view, partially in side elevation and partially in vertical section of the stationary or fixed head member.

Referring now to the drawings in detail, it will be seen that the `mbodiment of the invention (Cl. 15S-27.4)

(not shown). These tubes communicate with the annular channels 3 through angular ducts l in the stationary member 1, the tube 4 communieating with the comparatively large innermost channel, the tube 5 communicating with the in- 50 termediate channel and the tube 6 communicating with the outermost channel, as illustrated to advantage in Figure 6 of the drawings. As can be seen in Figure 3, the heating oxygen and acetylene are mixed by having the outermost and inter- 05' mediate channels each communicating with both the heating oxygen and acetylene ducts.

Hingedly mounted, as at 8, on the stationary member 1, is a swingable member 9 which, when in closed position, is in spaced, opposed relation to the ground face 2 of said stationary member 1. The members 1 and 9 have formed transversely therein aligned counterbored openings for the reception of headedmale and female bolts l0 and 11, respectively. The head ef the female beu 11 'l5 fits snugly into its opening for retaining said bolt against rotation. As will be readily apparent, the elements 10 and 11 constitute coacting means for securing the hinged member 9 in closed position.

The reference numeral 12 designates the cir- 80 cular hub portion of a swingable copper nozzle 13 which is journaled on the female bolt 11 between the members 1 and 9. The face of the hub portion `12 which is adjacent the face 2 of the member 1 is ground and hasformed therein annular con- 35 centric channels 14 which register with the channels 3. It will thus be seen that by tightening the male bolt 1-0 in the female bolt 11, the nozzle -13 will be frictionally clamped in adjusted position. The faces of the hub portion 12 have 90 formed therein annular marginal rabbets 15 which accommodate integral annular flanges 16 on the opposed faces of the members 1 and 9. Of course, the hub portion 12 is also provided with a centrally located opening 17 which accommodates 95 the female bolt 11.

The outer end portion of the swingable nozzle 13 is tapered, as at 18. The reference numeral 19 designates ducts in the nozzle 13 which extend from the annular channels 14 to the free end of -100 said nozzle. A stationary plug 20 is mounted in the outer end portion of the cutting duct for different sizes of tips.

It is believed that the manner of using the invention will bereadily apparent, particularly toV those skilled in the art to which it pertains. AsY indicated in broken lines in Figure 1 of the draw-- ings, the nozzle 13 may be expeditiously adjusted to any desired position within a given range to successfully meet various conditions or require- 110.

` cured between the members 1 and 9 of the head.

As will be readily apparent, the ducts 19 in the 'adjustable nozzle 13 are in communication with although a preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:- n

A torch head of the class described comprising a stationary member having a counterbored transverse opening therein and including a substantially fiat face portion having spaced, annular, concentric channels therein, the stationary member further having ducts therein communicating with the channels, a hinged member pivotally mounted on the stationary member and adapted to be positioned in spaced, opposed relation to the fiat face portion thereof, the opposedl faces of the stationary member and the hinged member having annular, integral annular ianges` portion journaled on the female bolt between the stationary and the hinged members, said hub portion having a plurality of spaced, annular concent-ric channels therein registering with the ifirst-- named channels, said hub portion further having annular marginal rabbets therein accommodating the annular flanges on the stationary and hinged members, the nozzle having ducts therein extending from the channels in the hub portion to the free end of said nozzle.
